Number of dental problems have been effectively treated with the use of lasers since 1994. However the use of laser technology in the field of dentistry is cautiously optimistic. The laser which is specifically used in the oral surgery or dentistry is called as a dental laser.
What are the types of lasers used in dentistry?
- Soft tissue lasers- YAG laser a type of soft tissue lasers are used for surgeries of the soft tissue such as gingivectomy, biopsy, frenectomy, periodontal sulcular debriment and disinfection of the periodontal pockets. Cutting and hemostasis can be photo-thermally achieved with the use of CO2
- Soft and hard tissue lasers- a type of laser called as erbium lasers are capable in the treatment of both soft and hard tissue. A range of dental procedures with the use of these lasers can be done without the use of local anesthesia. The most general application of erbium lasers are in some of the procedures of the hard tissue such as bone cutting and creation of minimal mechanical and thermal trauma to the adjacent tissues.
How do lasers work in dentistry?
- Acts as a cutting instrument or a tissue vaporizer when used for the dental and surgical procedures
- The bond between the filling and tooth is strengthen when used to cure the “filling”
- The effects and heat source of the bleaching agents of the tooth can be increased by the laser if it is used for the procedures of teeth whitening
When do dentists use lasers?
- Tooth decay- To remove the decay within the teeth and to prepare the surrounding enamel for filling, the lasers are used.
- Disease of gum-Reshaping of the gums and bacterial removal during the root canal procedures require lasers
- Biopsy-In order to examine for cancer, a small piece of tissue can be removed with the use of lasers
- Removal of lesion- Mouth lesions and the pain associated with the canker sores are also removed with the use of lasers
- Whitening of the tooth– teeth whitening procedures which requires application of peroxide bleaching solution on the surface of the tooth requires activation by the energy from the laser.
What are the advantages of using lasers in dentistry?
- Decreases post- surgical morbidity
- Need for the anesthetics will be reduced
- Risks of electrosurgical procedures can be avoided
- Association of little bleeding and swelling after the soft tissue procedures
- Root debridement is found to be potential with the use of erbium lasers
- Aids in the effective removal of the microorganisms from the periodontal pocket
- Helps in preserving healthier tooth during the removal of cavity
